Nikon F 70-210mm lens

As opposed to the various f/2.8 versions of the 70-210 Focal length, the f/4 and slower versions of such lenses are marketed to amateurs, accounting for their price.

However, the Nikkor AF 70-210 f/4 variant is a two-touch system (dedicated focus and zoom rings), compared to the rest of the lens range, which utilizes a one-touch (push-pull) system for focusing and zooming.
